I misunderstood and bought this book thinking it followed production of one of the movies day by day, from start to finish. This is not the case; basically, it's 365 pages of various special effects and sets (models, CG, miniatures, matte paintings etc.) with brief descriptions of each. It's fascinating reading (I had no idea how much work went into each scene, and am now more in awe of the artists who created these fantastic worlds than of the actors), though I would have liked more information about many of the photos than was provided.
It's also clear that the author was not a participant in the original three productions (IV, V, and VI)--his coverage of these is less extensive than the new movies of which he was a part, taking up only 116 pages--less than half--of a book that covers the six movies (episodes I, II, and III get 249 pages). Being an old school Star Wars fan, I preferred Lorne Peterson's Sculpting a Galaxy for its thorough coverage of the special effects of the early films.
My one complaint with this book is that the author acquired a new toy--a digital camera with a fish-eye lens--and drastically overused fish-eye photos in the last half of the book. I find the photos taken with the fish-eye lens almost dizzying, and it's very difficult to sort out what's truly where, when it's all spread out flat across a page. I really wish he'd limited these photos to only one or two, for sets that would be best shown with its perspective (a fish-eye view of a speeder cockpit??? Come on!).
The format of this book is also odd; only half as tall as a normal coffee-table book though just as wide, and about two inches thick; no doubt to make it the 365 pages the title claims. I would have liked larger pages that translated into larger photos--many are the size of thumbnails.
Overall, interesting reading, but not comprehensive.
